For WLAN access, Pegasus configuration described before for Pocket PC 2002 (Section 1.1 ) still works. A second way of configuration is also available using the default Pocket PC 2003 connection manager (Wireless Zero Configuration or WZC). 1.2.1 Automatic network detection The PPC 2003 connection manager scans for wireless networks periodically. When it detects any network and it has not connected to any network yet, it will first try to connect to one of the preferred networks. If such a network is not available or the connection manager can not connect to any preferred network due to invalid WEP key, it will popup a window and shows a list of networks for you to choose. See Figure 10. If you don t see the network of your choice, click on Settings to get to the detailed configuration window (Figure 14). Note: If the connection manager is able to connect to a network automatically, the Network Detection Window (Figure 10) will not appear, and you can follow the steps described in Section 1.2.2 to access the connection manager.

11 Figure 10 Network Detection Select your network and what the network will connect to. In most cases, you should select The Internet. If you are connecting to work network, select Work. If you do not wish to use the connection manager and would like to use the Pegasus Configuration GUI (Section 1.1 ) instead, click on Hide. Now click on Connect. If WEP is disabled, then the connection should be established, otherwise, a window will popup for you to enter the WEP key. Enter the WEP key then click on Connect. See Figure 11. The connection should be established. Figure 11 WEP key entry 1.2.2 Accessing the connection manager Click on the Connectivity icon to bring up the connection manager. See Figure 12.

If WEP is enabled on the AP, check the first checkbox, which is Data encryption (WEP Enabled). Now you need to obtain the WEP key and key index from your network administer, put the key string in the textbox labeled Network key, and select the Key index from the choice box (the default key index is 1). If WEP is not enabled, then leave the Data encryption unchecked. Click on OK to return to the previous screen (Figure 14). Figure 15 Configure Network Authentication 1.2.6 Connecting to an AP Tap and hold on the AP entry you wish to connect to, and select Connect option on the popup menu as shown in Figure 16. The LED on the WLAN module should start to blink, indicating it is trying to associate, and eventually turn green, which means it is connected successfully. The screen will also be updated to show the

14 new connection. See Figure 17. Figure 16 Connecting to an AP Figure 17 Connection to a new AP 1.2.7 Verifying network connectivity If the Pocket PC is not connected with a host PC via a sync cable, then the Connectivity icon normally indicates the WLAN connection is properly established. You can also check on the Network Adapters tab to check if the IP address obtained from DHCP is correct. See Figure 18, click SyChip Pegasus WLAN CF Module to see the IP address information (Figure 19).

15 Figure 18 Network adapter status Figure 19 IP address 1.2.8 Peer-to-peer mode Peer-to-peer mode is also known as the Ad-Hoc mode. There are two ways for your device to connect to other devices in peer-to-peer mode. The first way is that you create an Ad-Hoc network on your device, and then allow other devices to connect to yours by joining the network. The second way is simply connect your device to an existing Ad-Hoc network, if such network is already created by the peer device. 1.2.8.1 Creating an Ad-Hoc network from your device 1. Get to the Configure Wireless Networks screen as shown in Figure 14. Change the Networks to access choice box to Only computer-to-computer. Select Add New Settings under Wireless networks. See Figure 20.

17 Figure 21 Creating a new Ad-Hoc network 3. OK to go back to the previous screen. Click and hold the network name and select connect. Figure 22 Connecting to the Ad-Hoc network 4. Now the new Ad-Hoc network has been created, and it is visible to other WLAN devices. Your device is connected to the Ad-Hoc network as shown in Figure 23.

18 Figure 23 Connected to the Ad-Hoc network 1.2.8.2 Connecting other devices to the Ad-Hoc network Once the Ad-Hoc network is created, it is available for other devices to join. To join the network, go to the Configure Wireless Networks screen (Figure 22) using a second device. Repeat step 3 (Figure 22) and step 4 (Figure 23), the second device should now be connected to the newly created Ad-Hoc network, e.g. txtest. You can go to the connection Status screen (Figure 1) to find the devices IPs. The two devices on the same Ad-Hoc network should be able to ping each other. You can add more devices to the Ad-Hoc network by performing the same procedure so that they form a closed network among themselves.
